goodgeorge: I think, that this is exactly the area for MFT. Olympus or Panasonic 100-400 are about the same price, smaller, lighter and offer much better vesratility.

@Jon555

How does AF on 5DS R deal with subjects that occupy such a tiny part of the frame?

Also, why cripple your ability to capture action by using an expensive high megapixel FF camera when you can have much more capability with an APS-C Canon body at a fraction of the price?

While you are right and I would not qualify this lens as a system seller, it's still a nice addition for existing Canon users. One more option to get that extreme reach (for some limited set of circumstances, but still).

whitelens: For a number of reasons I would never buy this lens, but I have to admit I am really impressed. It is nice to see a company as conservative as Canon to design something so unusual!

I'll give Canon the credit for this. Nice for Canon users. While the compromises Canon made with it are crippling in many ways, at least it's an affordable option to go to extreme telephoto range with FF.

Normally to get that reach you had to go with big and heavy APS-C kit (with xxx-500 or xxx-600mm class of lenses) or more compact Micro 4/3 kit (with xxx-300 and xxx-400mm class of lenses).

Photo_Genius: I looked at flickr sample photos. In the real world you end up shooting at ISO 3200 or higher most of the time and the pictures look all very noisy. I had the Sigma 150-600 and a Canon aps-c and the shots look cleaner. But maybe it's because of the Flickr samples I don't know, I guess it's also because there is not much sunlight right know because of the winter.

EDIT: The dp review samples look much better, very clean shots, seems like a great lens for the price

https://www.dpreview.com/samples/1079091574/canon-rf-800mm-f11-is-stm-sample-gallery

If you shoot action at dawn, twilight or on a totally overcast rainy winter day, then sure, you will have to bump the ISO. But we're talking FF cameras here, where ISO 6400 is still nice and clean and you can push to 25600 on better bodies with careful processing.

But f/11 on a decent day is absolutely not a problem for an FF camera.

And if you're not shooting action, but something more stationary (bird on a tree branch for example), then f/11 is not a problem at all. I've been shooting my Olympus 100-400 with a teleconverter (that's 1120mm f/22 for equivalence folks) without issues with very low sun near sundown and sunrise.

williams359: 70-200 f2.8 would be nice

Ha, I saw. I really liked the idea of their 45/2.8 and seeing more of such lenses puts a smile on my face.

Now seriously, Panasonic should make an L-mount GX8 or something like that.

Also, Sigma, where's a new Foveon camera?

In reply to:

KCook: UWA for M4/3 please. Love their 10-20 on my Canon 50D.

That would be sweet, but unlikely to happen as Sigma does not make lenses that are strictly designed for MFT.

However, a 10-30mm would work great both on APS-C and MFT. A 9mm prime would also work great for both. Any of those would be super cool to see.

In reply to:

Kiwisnap: There are a number of "mirrorless camera systems" ranging from MFT to Medium Format.

Which one, Sigma?

Ideally more than one :-)

I'd like to see new Sigma lenses for MFT, APS-C and FF systems.

That's a good bet, me thinks.

In reply to:

lacikuss: Very few macro photos in this gallery, unfortunately.

You'd need a macro lens for that. Since this one is not really a macro, then all you can get is some closeups of the kind that systems with smaller sensors get with regular non-macro lenses.

The samples probably represent how this lens would typically be used.

In reply to:

DrCastle: I'd say 1:2(0.5x) reproduction ratio does deserve a "macro" naming. It's significantly better than what most lenses offer(0.1~0.25). I also really wish my e mount 85F18 had this kind of macro capability.

Well, the term macro has long been abused for marking lenses that can focus a bit closer than usual. But it's still misleading and not really impressive.

armandino: Interesting proposition, however when I think that for that money I can buy an A7RIV+200-600 (300-900 in crop mode @26MP) and there is plenty of change to spare makes me think that this is a pretty niche option.

@armandino
"The sample pictures here do not impress me, to be honest."

Me neither. I've seen way better photos taken with much cheaper consumer grade lenses. But you know why? Because the person behind the camera put great effort into taking those and actually had skills/talent/patience to capture good photos.

Those here are just snapshots. DPR sample shots are very rarely good photos. They are not meant to be, really. Sometimes they are even bad samples (like in this case, with just two shots at 500mm, both showing opposite result).

It's also substantially better in every way. That usually carries a premium.

davev8: for 1/2 this money you can buy and old sony 42MP A7rmkii (or a mki as crap AF won't matter and save more) a nice old 50mm F1.4 and get way better results and have a smaller package

@davev8
"on DXO go to DXO choose the lens and body goto measurements>sharpness> field map and see for your self"

No, to see for yourself, you need to take both cameras and take a photo.

For what you are suggesting, you probably don't even need to take the photos yourself.

Be careful, you might find that what DXO tells you and what reality shows don;t quite match up.

In reply to:

cd cooker: This new sexy 70-200 F4 gotta be Lens of the Year!

Are you asking if it makes sense to compare the price of an f/4 zoom to a price of an f/2.8 zoom?

A few years ago there was no point doing that, as everyone knew that you pay more for f/2.8 over f/4.

But now? When new f/4 zoom costs the same as an older f/2.8 zoom?

You have to ask yourself if that matters to you.

In reply to:

David610: Voigtlander Nokton 58mm f/1.4 SL II S for Nikon is much cheaper and produces superior images. It is also much smaller and lighter:

29mm f/0.8 φ72.3×88.9mm 703g 62mm filter size
58mm f/1.4 φ67.6x45.5 mm 320 g 52mm filter size

"produces superior images"

How do you know? I saw samples from that 58, the bokeh is really not nice at all, more similar to the 0.95 Noktons for MFT. Compared to Nikon 58, the difference in rendering is striking (and easily explains why Nikon users are willing to pay a huge premium for a lens that is considered garbage if you look at objective measurement metrics).

With sample photos from this Super Nokton being so limited and rather poor, you can't say much about the quality this lens produces.

In reply to:

Jon555: Seems expensive when a FF 40/1.4 via a speedbooster would be 28/1.0 and have AF...
(A 50/1.2+SB would be 35/0.9.)
Also a FF Voigtlander Nokton 58mm f/1.4 would be cheap enough to buy a mirrorless camera to go with it, let in more light and have some change left over.
Not saying it isn't interesting tho... but my 50/1.4 via SB is close enough for now...

But will such a combo produce similar results?

A lens is much more than its focal length and f-number.

There's lots of lenses where "you can buy xxxx for less money". And yet, those lenses exist.

Fathom a guess as to why?

s.seng: When did micro m43 overtook Leica as a posh system? All new lenses for this system are priced in multi thousand dollars. already two announced this week.

Around 2010, when Micro 4/3 lenses started appearing :-)

The better the lens, to more butthurt :-)

In reply to:

whitelens: Provided sample images are 1.9 MP.
I am sure modern MFT cameras have 20 MP.
Why would they provide sample pictures in such low resolution?

They always do that, I believe. And not only that, those samples are chosen quite poorly I would say. They really don't tell much about the character of this lens.

Voigtlanders for MFT are known for rather busy bokeh and nice sunstars. It would be good to know how this one fares in that regard. No ugly bokeh in those samples, but none of those are really pushing it in any way.

In reply to:

matsonfamily: i'm surprised that it doesn't have a chip to relay lens information.

Yes, this is very annoying, especially that Voigtlanders for Sony E mount do have that. And Cosina is a member of Micro Four Thirds consortium, so they have all the information they would need to do that.
